To alt whom it may concern:

Be it known that we, EDWARDA. BROWN and ALLEN WILLIAMS, citizens oftheUnited States, residing at Carbondale, in the county of Jackson andState of Illinois, have invented new and useful Improvements in Railway-Track Gages, of which the following is a specification.

This invention is a gage instrument forrepairing.

'2 is a top view.

An embodiment of the invention is illustrated in the accompanyingdrawings, in which Figure 1 is a side elevation thereof.

Referring specifically to the drawings, 6 indicates a beam having aspirit-level 7 on the top and at one end a series of steps or risers 8,

which are serviceable in leveling up the beam in working on curves whereone track is higher than the other. At the other end the beam has alaterally-extending cleat 9 to rest upon the rail and prevent theinstrument from falling over. At the same end the beam has a standard10, at the top of which is an arm 11, supported by a brace12. The arm 11is graduated, as at 13, to form a scale, and has an index 14, slidablethereon, to indicate the scale. 7

15 indicates a rod adjustable up and down across the beam throughaproper guide thereon and fixed at adjustment by a set-screw 17 is avertically-sliding foot at the other end of the beam, designed to restupon one of therails and support that end. of the beam when the same israised above the track. I

In use three of the gages above described I will be employed, the sightbeing taken from one to the other.

Thus'a straight track may be alined by setting three of the instrumentsalong the track and taking the sight across the uprights 10 at eitheredge'thereof, the three implements being placed any desired orconvenient distance apart. For working on curves to determine orindicate the de-' gree of curvature the three implements are Fig,

placed along the curve thirty-one feet apart and the sight taken fromthe standard -10 of the first device to the standard 10 of thethirdacross the arm 13, and the index being moved to the line will indicateon the scale the degree of curvature. It is obviousthat only one of thedevices need have an arm 11. Thf1 other twocan have simply the plainuprig t. I I

For elevating or surfacing a track the pin or rod 15 of the firstimplement is driven in a tie and the beam 6 raised by rule until at theheight wanted. The set-screw 16 is then tightened ,-and the foot 17 islet down until it rests on the rail. This supports the beam at theproper height above the track. Thethird beam is then raised tothe sameheight. The track under the intermediate beam, or the second beam, isthen raised until the beams are in line at the same height or on a levelwith respect to each other. Then by moving the instruments along thetrack to Patented March 13,1906;

new positions in a manner common to this class of devices the wholetrack can be surfaced or staked and brought tothe proper,

height. It will be understood that the uprights 10 on all the beams areof the same height and that the beams have the same dimensionsgenerally. The arm 11 can be reversed for left-hand work .by taking outthe 'bolts by which it .is attached to the uprights and turning itaround to the left side. The vertically-sliding foot 17 is fixed at thedesired height by a set-screw 18 and when not in use is drawn up besidethe lower edge of the beam. In connection with the spiritlevel the beamaffords means for leveling up a track and by the use of the steps forindicating the inclination of the track on curves. The upright 10 isperpendicular to the beam, and so forms a square.

"The device is capable of several other uses which will suggestthemselves to those familiar with the operation of such implements.
